Summary:
This adds support for `maintainVisibleContentPosition` on Android. The implementation is heavily inspired from iOS, it works by finding the first visible view and its frame before views are update, then adjusting the scroll position once the views are updated.
Most of the logic is abstracted away in MaintainVisibleScrollPositionHelper to be used in both vertical and horizontal scrollview implementations.
Note that this only works for the old architecture, I have a follow up ready to add fabric support.

Summary:
Normally when a `ref` prop supplied to a component is changed, the old `ref` receives `null` and the new `ref` receives the active component instance.
However, the current implementation of `ScrollView` has a bug where this does not happen (i.e. changing `ref` or `innerViewRef` does not cause either the old or new refs to be updated). This bug is due to a subtle issue with how `ScrollView` internally memoizes the `ref` (or `innerViewRef`) that is passed into the native component.
This commit fixes this behavior so that `ScrollView`'s `ref` and `innerViewRef` have the correct behavior.
Changelog:
[General][Fixed] When a ScrollView's `ref` or `innnerViewRef` changes, the old ref will now be invoked with `null` and the new ref with the active instance. (Previously, changing `ref` or `innerViewRef` on a `ScrollView` would be treated as though the ref had not changed at all.)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35169
This reorganizes typing structure a bit.
`Utilities.d.ts` was originally added for utilitiy types but I ended up leaving it a grab bag of types that didn't belong to any individual bit of code. Out of what is in it right now, `Insets` was actually public, and seems to have been imported.
We also run into files around the renderer which are [currently overwritten](https://github.com/facebook/react-native/commits/e286da25fc83324363486eb668806aca179f74b3/Libraries/Renderer/implementations/ReactNativeRenderer.d.ts) by the React sync script.
Finally, all of the top-level imports of `Utilities` were auto-generated by VS Code, but fail in real apps. I think this is because our tsconfig sets a `baseUrl` to allow resolution from the types folder, so the tooling in the RN repo will use that, but it breaks in real apps that don't have that mapping.
This splits all these up into a couple separate directories that are hopefully easier to reason about, and removes `Omit` which has been a builtin type for quite some time (we were actually already using built-in `Omit`).

Summary:
React Native's TS definitions are currently mostly stored in one monolithic file. This change splits the definitions up to correspond to the source files they came from, and are placed next to the source files. I think this should help inform, and make it easy to update the TS declarations when touching the Flow file.
I noticed as part of the change that the typings have not yet removed many APIs that were removed from RN. This is bad, since it means using the removed/non-functional API doesn't cause typechecker errors. Locating typings next to source should prevent that from being able to happen.
The organization here means individual TS declarations can declare what will be in the RN entrypoint, which is a little confusing. Seems like a good potential next refactor, beyond the literal translation I did.

Summary:
ScrollView has special-case logic to dismiss keyboard on tap, controlled via the `keyboardShouldPersistTaps` property. The first click does not propagate to children of the scrollview if the tap causes the keyboard to be dismissed. This behavior is motivated by a soft keyboard on phones which takes away space from the viewport.
ScrollView historically determined if a soft-keyboard was open via querying if there was a focused TextInput. This meant that clicks to a ScrollView would be eaten, even on form factors using phsyical keyboards.
A couple years ago I added https://github.com/facebook/react-native/pull/30374 to only eat clicks when keyboard events have indicated that a soft keyboard is present. I special-cased Android out of the change, because of platform issues with its reliability of keyboard events.
After D38500859 (https://github.com/facebook/react-native/commit/1e48274223ee647ac4fc2c21822b5240f3c47e4c) rolls out we can start to remove that special-casing, of devices which report "android" for Platform.OS.

Summary:
If currently focused on a TextInput, clicking an item in a ScrollView takes two clicks.
This is because of `keyboardShouldPersistTaps`, which will fire despite a lack of keyboard events on Android due to special-casing.
This behavior is jarring in scenarios like VR where the soft keyboard is detached from the application. This change avoids eating taps, in this case, where a soft keyboard is open but not inset.

Summary:
Changelog:
[General][Fixed] - Improved Flow type inference in Animated `.interpolate()`
Improves the ergonomics of `.interpolate()` by allowing Flow to infer the correct type for `outputRange`. This is achieved by adding a new type parameter `OutputT` to `interpolate()` (and `Animated.Interpolation` and `InterpolationConfigType`), which Flow infers as either `number` or `string` based on usage.
Admittedly, at the call site, this is not that much safer compared to something like `outputRange: $ReadOnlyArray<number | string>`, but it does document the intent of the API a bit better and provide some downstream type safety. For example, we can now express `Animated.Number` (D35869375) more precisely by excluding string-valued interpolation nodes.

Summary:
Retrying D30015799 (https://github.com/facebook/react-native/commit/6e903b07fa8e8d9b78cae0e031bb8022f7a63195) with a fix where ScrollViewNativeComponent was missing the automaticallyAdjustKeyboardInsets prop.
----- Original Summary
Currently, ScrollViews provide the prop `keyboardDismissMode` which lets you choose `"interactive"`. However when the keyboard is shown, it will be rendered above the ScrollView, potentially blocking content.
With the `automaticallyAdjustKeyboardInsets` prop the ScrollView will automatically adjust it's `contentInset`, `scrollIndicatorInsets` and `contentOffset` (scroll Y) props to push the content up so nothing gets blocked.
* The animation curve and duration of the Keyboard is exactly matched.
* The absolute position of the ScrollView is respected, so if the Keyboard only overlaps 10 pixels of the ScrollView, it will only get inset by 10 pixels.
* By respecting the absolute position on screen, this automatically makes it fully compatible with phones with notches (custom safe areas)
* By using the keyboard frame, this also works for different sized keyboards and even `<InputAccessoryView>`s
* This also supports `maintainVisibleContentPosition` and `autoscrollToTopThreshold`.
* I also fixed an issue with the `maintainVisibleContentPosition` (`autoscrollToTopThreshold`) prop(s), so they behave more reliably when `contentInset`s are applied. (This makes automatically scrolling to new items fully compatible with `automaticallyAdjustKeyboardInsets`)
## Changelog
* [iOS] [Added] - ScrollView: `automaticallyAdjustKeyboardInsets` prop: Automatically animate `contentInset`, `scrollIndicatorInsets` and `contentOffset` (scroll Y) to avoid the Keyboard. (respecting absolute position on screen and safe-areas)
* [iOS] [Fixed] - ScrollView: Respect `contentInset` when animating new items with `autoscrollToTopThreshold`, make `automaticallyAdjustKeyboardInsets` work with `autoscrollToTopThreshold` (includes vertical, vertical-inverted, horizontal and horizontal-inverted ScrollViews)
